Tru-maxx 66253255167 Grinding Wheel 8 in 80 Grit

Product Description

The TRU-MAXX 66253255167 is a Type 1 bench and pedestal grinding wheel designed for general-purpose stock removal and tool sharpening on bench grinders and pedestal grinder units. The wheel measures 8 inches in diameter, 1 inch thick, with a 1-inch arbor hole, and carries an 80-grit medium grade for balanced material removal without excessive surface aggression. It is bonded with a vitrified bond and manufactured from semi-friable aluminum oxide abrasive, making it well-suited for ferrous metals, tool steel, and similar hard materials. Licensed tradespeople and experienced metalworkers install this wheel as a standard service replacement or initial setup component on stationary grinding equipment.

This grinding wheel fits standard 8-inch bench and pedestal grinders commonly found in maintenance shops, machine shops, fabrication facilities, and tool-and-die operations. The 1-inch arbor hole is the most common bore size on this class of machine. Rated at a maximum of 3,600 RPM, the wheel is matched to the typical operating speed of 8-inch bench grinder motors. No bushing is included; reducers or bushings must be sourced separately if the machine spindle diameter is smaller than 1 inch.

Installation Notes

Wheel mounting should be performed by a qualified operator following ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels. Always power down and lock out the grinder before removing or installing a wheel. Inspect the wheel for cracks or chips before mounting, and ring-test it per standard procedure. Do not exceed the 3,600 RPM maximum speed rating marked on the wheel, and always use the appropriate guards and eye protection during operation.
